G l ASS-CUTTING KECHANIBI.

Specication of Lettera Patent.

Patented Apr. 1, 1919.

To all whom it may concern:

Be it known that I, GEO. P. MACNICHOL, a citizen of the United States of America, residing at Toledo. Lucas count Ohio, have invented new and useful lass- Cutting Mechanisms, of which the following is a specification.

This invention relates to cutting and severing mechanism.

his invention has utility when embodied in devices for determining definite lengths of material as glass in a quick and accurata manner,

Referring to the drawings:

Figure 1 is a plan view with parts broken away of an embodiment of the invention as a ang cutter;

`ig. 2 is a side elevation of the mechanism 0f Fig. l.;

Fig. is a secou on an enlarged scale on the line IIL-lll, Fig. 1, looking in the direction of the arrow; l

Fig. 4 is a section on the line V-IV, Fig. 3. looking in the direction of the arrow, showing the heating mechanism only;

Fig. 5 is a section on the line V-V, Fig. 1, looking in the direction of the arrow;

Fig. 6 is a detail in lan of one of the ware progressing sustaining rollers; and

Fig. 7 is a side elevation of one of theI sectional holders with parts broken away.

Mounted upon the sustaining rod 1 are the boxes or upper section holding elements 2 anvil the lower hinged holding elements 3. These sections 2, 3. of the holder carry removable bushin .fs 4 which may be of a size to conform to t e article or ware being cut. The mechanism is especially designed for handling articles of cylindrical contour as tumbler-s. lamp chimneys, tubing, etc. The bushings 4- are shown engaging the glass tuhe 5. Fig. 7. In the handi ware, it is desirable to have the bushin 1n more than one part or in se :irate sections, say as shown in Fig. 7. o assist in the proper centering or holding of the ware these bushings 4 are shown as provided with stems 5 with which s rings 6 coact as comll. The adjustment of the plugs 7 serves to determine the force of the ping action against the ware being han led).

From the source of energy, as generator 8, lines 9, 10, leadto the terminals 11. 12, re-

I6 sppetvely, in the holder sections 2, 3. As

ng of certain shown in Fig. 3 there are two sets of b ushings 4 in the complete holder 2, 3, said sots being slightly spaced to form an annular groove therebetween. The block 13 adjusted y the screw 14 .takes tliecurrent from the line 11 and delivers to the hot wire 15 extending to the block 16 on the opposite side of the section 2 from the block 13. With the blocks 2 and 3 against each other the block 16 contacts a similar opposing bloclil 17 to close the circuit from wireY i5 to wire 1S con nected to the block 19 to which is attached the terminal 12 of the linel ,10. The circuit is accordingly completed and eerv to heat the Wires 15, 18. held just outside or away from the ware 5 b the adjustable hlals 13, 19, 16. 17. These lieating mechanisms or hot. wire half circles 15, 18, also just clear the hushings 4 on each side thereof.

With some kinds of wire 15, 18, and in the handling of certain ware, the device dia closed is sufficient to insure a proper severing. However, as an additional safeguard and of considerable advantage with some sizes of wire a further localizing of the heat zone is to purpose. This is accomplished h v keeping the bushings cool say by circulation of water through the chambers of the holder sections 2, 3. For instance, the supply line 20 has branch 21 leading to the lower part of the chamber of section 2 and discharging by line 22 from the upper art of section 2 into the return line 23. or cooling the lower and relatively movable holder section 3 the flexible duct 24 from the supply line 20 delivers water to the lower part of the chamber of the holder 3, which water is discharged therefrom into the llexi ble duct 25 -leading to the return water line 23. L,

In the handling of ware, especially tubing, there may be slight deviations i direction or in diameter. The yieldable bus i 4, to an extent, will care `for such deviations. However, as anrther check the holder soetions 2, 3. have their bushin 26 coacting with the shaft 1 yieldable as seterminod by the springs 27. These yieldable features have additional utility `in the rotation of the ware during heating. which rotation is desirable in the instances where a strai t cut surrounding a cvlndrical object is osired. When so handled, the cut or severing is accurate and furthermore there is not a disturbance of the glass away from the cut .Adapted to extend eireuniferentialibvv around .2e 'ware and having yieldable gripping i c engaging the Ware, a eoolin liiiid circulating system connected with lsaid hollow sections, a. heating element disposed between said gripping members and around the ware, and means for rotating the ware within said holder.

7. A device of the class described, coinprising the combination of a ware holder` iiicluding a plnriilityof hollow sections adiipted to extend rirrinnferentially around the were and forming llilid circulating chambers, the inner walls of wliieli are provided with cooling extensions projecting" radially into said chaniliers, gripping members between the Ware and said sections, and heating means disposed between said gripping niembers and around the were.

8. A devia: of the class described, coniprising the combination of a ware hold/er, in cluding` a plurality of hollow sections adapt-- ed to extend eircumferentially aroniid the ware and forming Huid circulating chambers, the inner walls of 4which are provided with hollow cooling extensions projecting into said chambers, gripping members` between the were and safl sections having stems projecting into the extensions, means engaging said extensions to hold the gripping members in yielding engagement with Said ware, and lieiitiiig meansinterposed between said gripping members and around the Ware. f

9.A device of the class described, ooiiiprising a, ware holder formed of a pluralit)1 of hollow sections adapted to extend circumferentially around the ware, a fluid i-ii'riiQ latiiig system connected with said hollow sections, heating mechanism for the ware located between said sections. and means for rotating said ware between said sections.

10. A device of the class described, coniprisiiig a ware holder formed of a plurality of yieldingly connected sections adapted to extend circuiiifcrentially around the ware andeach provided with one or more radial sleeves, gripping members for the ware having stems projecting into said sleeves, and springs yieldingly forcing said gripping members in Contact with the ware.

11. A device of the class described, comprising a ware holder formed of a plurality of sections adapted to extend circuiiiferentially around the ware and each provided with one or more radial sleeves, gripping members for the ware having stems projeoting into said sleeves, springs yieldingly engaging said stems, means for tensioning said springs,'and heating means disposed between said gripping members and around the ware.

In witness whereof I affix my signature in the presence of two witnesses.
